There are many keys you can use to make your game playing more efficient:

Space

Auto-finish—In foundation games, this moves all the cards it can up to the foundations

z

Undo

x

Redo

n

New Game

g

Replay the same game

There is also a card-finder keyboard feature you can use to help you locate cards:

a

Highlight the aces

1 though 9

Highlight the cards with the rank pressed

0 or t

Highlight the tens

d, c, h, s

Highlight the cards with the suit

r, b

Highlight the red or black cards

You may combine the rank keys with the suit or color keys. For example, if you hold down the "5" key and
the "d" key then only the 5 of diamonds will be highlighted. "a" and "r" will highlight the red aces.
